about 2 weeks ago I came home from vacation my neighbor had been taking care of my flock and I noticed while I was gone he cleaned out my coop and run with a hose and it was a swamp for about a week. but I noticed some runny poop that had a yellowish color to it and 2 days later one of my barred rocks was not moving and could barly hold her head up. with in 24hrs she had died. I started to add apple cider vinegar to the water but now 2 weeks later I noticed my RIR had alot of crap stuck on her backside under her vent. she is still fairly active but its almost looks as if she is constipated and can't poop. any advice would be helpful as i am concerned for the flock and at a loss
thank you
